This is a picture of the PCB for a Tile Bluetooth tracker.

I cant find any info on this chip, and I've looked for a while for the logo. here is a closer picture. The logo looks like three ticks, does anyone have any ideas? It should be some sort of RF front end for the Bluetooth.

Edit: I think The Photon correctly identified the logo as that of RFMD, but I'm still having trouble finding the exact part, especially since they got acquired

From what I can tell, Pin 4 is the connection to the bluetooth IC and pin 11 is the connection to the antenna. Pins 3 and 10 are connected to GND, and beyond that its not clear.

Finally found it! It's the RFFM6205, and the important code on the package is X8

  • \$\begingroup\$ yupp, thats definitely the one, now I just need to figure out the part number \$\endgroup\$ – BeB00 Sep 13 '18 at 23:31
  • \$\begingroup\$ Given time someone here will know that number or at least the manufacture. Then a search is easy. \$\endgroup\$ – Sparky256 Sep 14 '18 at 3:14

Reverse-engineering some of the traces to try and determine a feasible pinout could be useful.

Could be something like this, a Wi-Fi/BT integrated front-end module. Comparing the pinout of similar ICs to what you have should be a good indication of if you're on the right track or not.
